I'm truly at my wits and either COX, I cannot Express my disdain for this company in words. I have not been able to use Shareplay on my PS4 since being graced with this ISP. I have called and talked to multiple COX reps about my issue and none can help me so naturally into to my networking friend and Google for help, and when I say I've tried everything we could come up with, we've tried everything, port forwarding/triggering(got port numbers from sony), DMZ, swapped routers (tried 2 Cox issued modems and then purchased my own modem/router combo by netgear, I can provide model numbers when I get home if it helps) i tried a static IP but i don't think I ever got it to work correctly and I tried bridging my modem to my linksys router and they just successfully exploded the net and I had to set everything to factor and start again, I'm hardwired with CAT6 eilthernet cables, now with my personal modem I AM clocking constantly higher speeds than the issued modem but i still cannot use shareplay, its beyond frustrating, I have PS plus and both my friend and I have speeds WAY over the required. I tried to ask for help on Cox Twitter and they were worst than the phone representatives believe it or not. I did see a post up here of someone having a similar issue 10-11months ago and they resolved it by getting their own modem, I'm curious if it worked for them because it wasn't a modem/router combo or if it was before Cox started blocking ports I assume its cause port 80 is blocked which would explain why my port forwarding and DMZ didn't work, if Cox isn't sending the signal at all,opening the ports wouldn't do anything anyway but Cox will not tell me for sure if that is the reason or not I have no clue I'm just making a guess based off the googling I did. Does anyone know why it's not working? And maybe if I'm lucky a solution?? Or am I just screwed to never be able to host a shareplay in the state of NV since they are the only ISP here with speeds fast enough to even game on in the first place x.x (which ** cause I'd really love to never use Cox again) I can join shareplay's my friends host but can never host one x.x I'm going to pull my hair out with this. Can they really block a whole feature from everyone?!
I would start by you and your friend enabling the routers to be pingable through the WAN IP and then try to ping each other. Besides that, could you show a screenshot of your portforwarding? Port 80 shouldn't be needed for inbound, only outbound. If outbound port 80 was blocked you wouldn't be able to bring up any websites. Last, is there a document you are following the instructions for?
PS. I don't have a PS4 so feel free to wait for a reply from someone who has and has tried Shareplay.
I'll take any help I can get the! Here ya go, and I'll have to figure out how to get my friend and I to ping each other I'm not feeling confident that it will be successful but nothing ventured, right? Added should be the ports I forwarded well least tried to
ok, i got the new modem i'm going to see if it works first then open ports/do the ping test, Model number CM1000 by netgear and linksys router ac 1200+ model number EA6350

sadly still didnt work, here are my ports forwarded and when i run the pin thought my router it turns out fine,when i use https://www.ipfingerprints.com/ping.php it looses everything, which leads me to believe i can ping my own systems inside my own network but inbound traffi just cannot get through, im going to call linksys tomorrow just to make sure my router is applying the changes and i had Sony rebuild my PS4 additionally, when i tried to go to the setting on my new modem there are basically nothing on it, is that standard for just modems? i'm going to call them as well tomorrow to check, i just wanted to leave an update here (i also only use the ports sony gave me this time and left out the others i tried last time)

Did you try connecting the PS4 directly to the CM1000? If that doesn't work, you know it's not a router problem.
I got it working!! after trying it connected to my modem it still didnt work so i contacted linksys and had them flash my router redid the port forwarding and it still didnt work, so i had linksys's send me out another router of the same kind to fully rule out the router not working properly and it worked with the new one!! so my official fix for this is to get a stand alone modem and router and forward the ports. apparently "gateway" modems just dont cut it like you said. :D thank you for all the help!
Great job! Sorry I wasn't much help solving the problem but good job solving it yourself!
